Justinian II of Byzantium

Justinian II of Byzantium (669-11 December 711) was the Emperor of the Byzantine Empire from 685 to 695 (succeeding Constantine IV of Byzantium and preceding Leontios of Byzantium) and 705 to 711 (succeeding Tiberius III of Byzantium and preceding Philippikos of Byzantium).

Biography
Justinian was born in 669 to the House of Herakleidon, and he succeeded his father Emperor Constantine IV of Byzantium upon his death in 685. He reigned for ten years, but strategos Leontios ousted him in 695. The Twenty Years' Anarchy followed, and Justinian regained power from Leontios' own ouster Tiberius III of Byzantium. Justinian reigned from 705 until 711, when he was overthrown by the future Philippikos of Byzantium, who gathered an army of Khazars and forces from Cherson to overthrow him. His own army of 100,000 Bulgars and Slavs betrayed and killed him.
